The package diffalg provides basic functionality for computations within differential polynomial rings in n indeterminates over . Currently, these rings are realized by using doubly indexed indeterminates where the first index distinguishes the indeterminates and the second index denotes the order of the corresponding derivative.
The differential polynomial with and where we consider only orders up to 20 is defined as follows:
Use S::=Q[x[1..2,0..20]]; F:=x[1,4]^2-x[2,4]^3;
